Are you considering the 551 Holographic Sight, Tactical Metal Green & Red Dot Sight Scope to upgrade your optics and wondering how it will perform in real use?
First Impressions
The first time you handle the 551 Holographic Sight you’ll notice the metal frame and compact footprint. It looks like a thoughtfully designed reflex sight that aims to give you bright optics without hogging your rail space.
Packaging and Unboxing
When you open the box you should find the sight secured in foam or a molded tray, usually with mounting hardware and an instruction manual. You’ll want to check the package contents right away to confirm anything that should be included, like lens covers or a cleaning cloth, and to ensure there’s no shipping damage.
Build Quality and Materials
The product description emphasizes a metal frame and shockproof, weatherproof materials, which is reassuring if you plan to subject your gear to rough conditions. You’ll appreciate the solid feel when mounting the sight, and the metal housing helps reduce flex and potential misalignment under heavy use.
Optics and Reticle
This sight is designed to give you a bright aiming point with user-selectable reticle colors and multiple brightness levels. You’ll want to test the reticle in different light conditions to find your preferred settings.
Multi-layer Coated Lenses
Multi-layer coated lenses are included to improve light transmission and reduce glare, which helps keep the dot crisp and easy to pick up. You’ll notice fewer internal reflections and better contrast between the reticle and the target compared to uncoated optics.
Reticle Options (Red/Green)
A simple switch lets you change the reticle color between red and green, which is useful depending on ambient lighting and target background. You’ll find green easier to see in bright daylight and red better in dimmer conditions, so having both choices makes the sight more versatile.
Brightness Levels and Settings
There are 10 brightness settings so you can dial the dot up for bright sun or tone it down for twilight and indoor use. You’ll want to practice adjusting brightness quickly so the dot isn’t washing out or becoming a faint ghost when you need fast target acquisition.

Performance in the Field
Actual field performance is where a sight proves its value, and this unit aims to deliver consistent, bright optics with a stable reticle. You’ll evaluate its usefulness across different scenarios, from short-range dynamic shooting to casual plinking.
Daylight Performance
In full daylight the multi-coated lenses and high brightness settings should deliver a vivid dot that stands out against varied backgrounds. You’ll likely prefer the green dot in bright conditions since human eyes often perceive green at higher apparent brightness.
Low-Light and Night Use
At dusk or indoors the lower brightness settings become important so the dot doesn’t bloom or mask fine details. You’ll want to verify how low the dimmest setting goes and whether the dot remains crisp without creating a halo effect that can obscure small targets.
Parallax and Accuracy
Reflex sights usually have minimal parallax at typical engagement distances, but you’ll still need to test this sight at the distances you normally shoot. You’ll want to confirm the sight maintains a consistent point of aim when your eye moves around the sight window.
Recoil and Shock Resistance
The shockproof materials and metal frame are meant to keep the sight aligned even under recoil, which is important if you mount it on higher-powered firearms. You’ll want to check zero retention after a live-fire session to confirm the sight maintains its adjustments.
Mounting and Compatibility
You’ll be installing this sight on a 20mm tactical rail, and the product is advertised to be compatible with that standard. Proper mounting and secure tightening will help you get repeatable accuracy.
20mm Rail Fit
The sight is compatible with any 20mm tactical rails, meaning it should slide into standard Picatinny or Weaver rails depending on your system. You’ll want to verify the clamp or mounting screw engagement and ensure there’s no wobble once it’s tightened.
Using with Magnifiers and Backup Sights
Because of its compact design there’s extra rail space left for a magnifier or iron sights behind it, and many shooters mount a magnifier to gain quick target ID at medium ranges. You’ll test co-witness alignment if you plan to use backup iron sights or align the sight with any flip-to-side magnifiers to ensure the reticle remains centered in the field of view.

Controls and Ease of Use
User-friendly controls are key when you’re under time pressure, and the simple red/green switch plus brightness steps aim to keep operation straightforward. You’ll appreciate tactile or clearly labeled controls that are easy to manipulate with gloved hands.
Power and Switch
The sight offers a basic on/off and reticle-color switch that should be intuitive to access. You’ll want to familiarize yourself with the control location so you can change settings without needing to take your aim off target.
Battery and Runtime
The listing doesn’t specify battery type or exact runtime, so you should check the product details or the manual for battery information before relying on it for long missions. You’ll benefit from using a fresh, recommended battery and carrying a spare so you don’t lose power at an inconvenient time.
Durability and Weather Resistance
The sight is built to resist shock and weather, which matters if you take your gear into changing environments. You’ll be more confident using the sight in wet or dusty conditions when its protection level is robust.
Shockproof Construction
Shockproof materials and a metal frame combine to protect internal components from sudden impacts and recoil forces. You’ll still want to inspect mounts and screws periodically to catch any looseness early, but the sight is designed to take a beating and keep working.
Weatherproofing Details
Weatherproofing is indicated, though the precise rating (IP rating) isn’t provided in the product text. You’ll want to keep a routine check on the lens seals and enclosure to ensure moisture isn’t able to creep in after heavy exposure to rain or mud.

Size, Weight, and Ergonomics
A compact reflex sight is usually designed to keep your rifle balanced and leave room for additional accessories. You’ll notice how the sight affects balance once mounted and whether it comes close to interfering with your handling.
Compact Design Benefits
The compact design reserves space on your rails for other accessories and keeps your optic low-profile. You’ll appreciate not having a bulky sight that interferes with glimpses of backup iron sights or mounting points for a magnifier.
Balance on Your Rifle
Because it’s not oversized, the sight won’t move the center of gravity too far forward, maintaining your rifle’s handling characteristics. You’ll feel the difference especially if you’re used to lightweight setups and rapid transitions.
Accessories and Compatibility
You’ll likely pair the sight with a few accessories depending on your role—magnifiers, flip-up lens covers, and rail-mounted lights are common companions. Ensuring compatibility ahead of purchase can save you time and money.
Common Accessories and Fitment
Lens covers, a magnifier for medium-range engagements, and a quick-detach mount are common accessory choices for reflex sights. You’ll also consider anti-reflection devices or shades if glare is an issue in high-sun environments.
What Works Well Together
This sight’s compact form factor makes it a natural match with low-profile quick-detach mounts and 3x magnifiers on a flip-to-side mount. You’ll want to test how quickly you can transition between magnified and unmagnified views if you use a magnifier behind the sight.
